Jerk motion when letting off throttle

I just got a 2003 zx6 636. Runs good, but when I let off the throttle, there's kind a jerk motion. Not sure if it's normal or not for these bikes, but it's a pretty good size jerk. Not sure what it could be. The bike did sit for a couple years, but has less than 5,000 miles. Doesnt jerk when the clutch is engaged and the throttle is let off.

Any ideas?

Thanks!

Chain is pretty good. Maybe a little more on the tighter side of the recommended play.

If you just chop the throttle, yes, you will be pitched forward due to engine braking. This is normal. Turning the idle up just a little may help with this.

Put some Seafoam in the tank and ride it for a while and see if that helps. It may clean things up a bit. It is fuel cleaner, it has helped a number of my bikes. Especially ones with jets and such.
